Short answer. No, not if you're a natural person party. Rule 132, Section 15 lets the court exclude witnesses so they can't hear each other's testimony, but it expressly does not authorize excluding a party who is a natural person, a juridical entity's designated representative, or anyone whose presence is essential to a party's case.
What the law says
The court motu proprio or upon motion, shall order witnesses excluded so that they cannot hear the testimony of other witnesses.

The general exclusion-of-witnesses rule
Rule 132, Section 15 lets a court order witnesses excluded from the courtroom so they cannot hear each other's testimony. It states that the court motu proprio or upon motion, shall order witnesses excluded so that they cannot hear the testimony of other witnesses. This is the general power the rule creates, and it is the provision the other side is presumably invoking when they ask that you be excluded during witness testimony.
The exception for a party who is a natural person
But the same section immediately limits who that exclusion power actually reaches. It states plainly that this rule does not authorize exclusion of (a) a party who is a natural person. If you are a party to the case and a natural person — as opposed to, say, a corporation appearing through a representative — this exception applies to you directly, and the exclusion-of-witnesses rule simply does not authorize the court to exclude you from the courtroom on that basis.
The other three exceptions
The article lists three other categories the rule also does not reach: (b) a duly designated representative of a juridical entity which is a party to the case, (c) a person whose presence is essential to the presentation of the party's cause, or (d) a person authorized by a statute to be present. Together with the natural-person-party exception, these four categories are carved out of the exclusion power entirely, regardless of whether they are also going to testify as witnesses.
What the court can still do about witnesses
None of this stops the court from managing witnesses more generally. The article also allows the court to cause witnesses to be kept separate and to be prevented from conversing with one another, directly or through intermediaries, until all shall have been examined. So the court retains control over ordinary witnesses hearing or discussing each other's testimony — the limitation is specifically on using that power to exclude you, a party who is a natural person, from your own case.
